To aZZ whom it may concern.-

Be it known' that we, FREDERIO O. SAYLES and OTIS E. DRQWN, citizens of the United States, and residents, respectively, of Pawtucket and Lincoln, county of Providence,and State of Rhode Island, have invented an Improvement in Machines for Singeing Fabrics, of whichthe following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts. I o

This invention relates to that class of machines employed for removing the superfluous fibers from laces, cloth, and other textiles wherein a singe-plate is used, upon and over which the material to be singed is passed.

Our invention relates to machines for singeing laces, cloth, and other textiles wherein a heated singe-plate' is employed; and it has for its object to provide forthe heating of the singe-plate by means of flames of mixed gas and air directed against one side, preferably the under side,of the singe-plate,and inclosed or confined in a box having an upper heating chamber, of which the said singe-plate forms the top, and a lower chamber having a series of openings in its top leading into said upper chamber, the said box having a series of gassupply pipes extending into the lower chamber,with their exits or orifices at the openings in the top of said lower chamber, and having a series of air-supply pipes opening into said lower chamber. The box is further provided with openings communicating with' a smokepipe; also with side chambers through which the air -pipes pass before communicating with the lower chamber of the box, so that the air may be heated in its passage to said lower chamber.

i The invention is fully described in the following specification, and is particularly pointed out in the claims.

Figure 1 is a vertical longitudinal section of a machine embodying our invention; Fig. 2, a section on line 00 m, Fig. 1; Fig. 3, a plan view partly in section and partly broken away; Fig. 4, adetail to be referred to, and Fig. 5 a sectional elevation infull online 3 y, Fig. 1.

The frame-work A, having the rolls 2, 3, 4,

5 and 6, the tank B, having the partially-sub- 5o merged roller 1), and the friction or drawing rolls 7 8, the former being provided with the fast and loose pulleys 9 10, are and may be of usual or preferred construction.

As the present machine contains two singeplates to remove the superfluous fibers from both surfaces of the cloth passed over them, and as both singe-plates and accompanying mechanism are alike in construction and operation, the description for the present will be limited to the lower singe-plate and its parts.

.0 is the lower singe-plate, forming part of the metal box or heating-chamber G, which is bolted to the framework A, as shown at c, Fig. 1. upper heating-chamber, d, two side chambers, d, and a lower chamber, d The singe-plate 0 forms the top of the upper chamber, d, and the walls of said chamber have openings 6,

leading at its ends into the smoke-pipe H, 7:,

and other openings, 6, leading into the side chambers, d. The top of the lower chamber, d is provided with a series of openings, 6 leading into the upper chamber, d. A supply of hydrogen gas flows from a suitable reservoir or gasometer (not shown) through the pipe E, thence into the branch pipe f, and into the individual jet-pipes f, having stopcocks f, the said jet-pipes f extending into the lower chamber, (throngh'openings in the A supply of atmospheric air is provided by means of the blower G, whence it flows through the pipe 9, (see Fig. 5,) extending down into the smoke-pipe g, to the lower end thereof, where it is divided into two branches or pipes, 9 (see Figs. 3 and 5,) which extend 0 through the side chambers, d, (see Fig. 1,) and out at the opposite ends thereof, thence below said chambers, (see Figs. 1 and 5,)where they'communicate with the lower chamber,

01 by means of the short connecting-pipes g the openings of which are clearly shown in Fig. 2. The openings (2 in the top of the lower chamber are larger than the jet-pipes This metal box is provided with an 65 f, so as to permit currents or jets of air to pass around the gas-j ets and flow through said openings with the gas, thereby providing, when the gas is ignited, a flame of intense heat, altogether free from soot, which is directed against the under side of the singeplate 0 to quickly heat it to the required degree. By having the air-pipes communicate with the lower chamber and the gas-pipes to extend into said lower chamber, with their orifices at the openings in the top thereof, the gas as it issues from the gas-pipes passes through the orifices in the said top of the lower chamber in individual jets, which are surrounded on all sides with strong, even currents of air which pass through said orifices from the lower chamber to the upper chamber, whereby,when said jets of gas are ignited, their intensity of heat is largely augmented by the mingling therewith and combustion of the heated currents of air, and said flames thereupon acting on the singeplate in a sub stantially-confined space, the heat is utilized in a very economical manner, and serves to quickly and thoroughly heat the singeplate to the required degree for effective work. The products of combustion pass through the openings e at the end of the upper chamber directly into the smokepipes H and g and through the openings 0 into the side chambers, whence they pass through the opening 9' (see Figs. 2 and 4-) into said smoke-pipes H and 9. For this purpose, and as shown in Fig. 2, the side and lower chambers are of greater length than the singe-plate and upper chamber. The air-supply pipes are carried through the side chambers to thoroughly heat the air before it flows into the lower chamber, the purpose of which is obvious.

The upper singe-plate, K, is provided with air and gas supply pipes, chambers, and other parts exactly like those described in connection with the lower singe-plate, except that the air-supply in this case flows from the blower G through the pipe 9 which passes down into the smoke-pipe H, and thence branching and extending into the side chambers pertaining to said upper singe-plate.

WVhen the apparatus is in operation and the singe-plates properly heated, the cloth is carried about the rolls 2 3 and over the lower singe-plate, O, with the under surface of said cloth in contact with said singe-plate, thence about the rolls 4 5, and over the upper singeplate, with the upper surface of the cloth touching said upper singeplate, when the superfluous fibers will be thoroughly removed from the cloth, after which the said cloth is carried about the roll 6 over the wet roll I) and about the friction or drawing rolls 7 and S in usual manner.

\Vhat we claim is- 1. The combination, with a metal box having an upper heating-chamber, a lower chamher, a singe-plate forming the top of the upper chamber, and the lower chambenbeing provided with a series of openings 111 Its top leading into the upper chamber, and with mechanism for passing cloth or other textiles over the s'ingeplate, of a series of gas-supply pipes extending into said lower chamber, with their exits or orifices at the openings 1n the top of said lower chamber, and a series ofalrsupply pipes opening into said lower chamber, substantially as set forth.
